[Ruby] IBM's search method of choice

Inori · 05-10-2015, 09:22 PM

I was clicking around, trying to find stuff to add to Envoy (big update on the way) and I found this on IBM's site. It's fairly basic, but it works like a charm (usable cross-platform, no Gems needed).

Code:
require 'find'

puts ""
puts "-----------------------File Search-----------------------------------"
puts ""
print "Enter the search path    : "
path = gets
path = path.chomp
puts ""
print "Enter the search pattern : "
pattern = gets
pattern = pattern.chomp
puts"----------------------------------------------------------------------"
puts "Searching in " + path + " for files matching pattern " + pattern
puts"----------------------------------------------------------------------"
puts ""
Find.find(path) do |path|
    if FileTest.directory?(path)
        if File.basename(path)[0] == ?.
            Find.prune       # Don't look any further into this directory.
        else
            next
        end
    else
        if File.fnmatch(pattern,File.basename(path))
            puts  "Filename     : " +  File.basename(path)
            s = sprintf("%o",File.stat(path).mode)
            print "Permissions  : "
            puts s
            print "Owning uid   : "
            puts File.stat(path).uid
            print "Owning gid   : "
            puts File.stat(path).uid
            print "Size (bytes) : "
            puts File.stat(path).size
            puts "---------------------------------------------------"
        end
    end
end

where would this rb script be useful for anything practical

If you've tried it, you would know.

It's (probably) a more advanced and in-depth version of your run-of-the mill stock search tool that comes packaged with your OS/distro. It's especially useful for people who want to run a file search in their shell/command line, which can be accomplished by requesting ruby search.rb (if that's what you named the file).

but if you want to search for a file in a cli shell then you can just use which, find, or for windows, dir
http://unixhelp.ed.ac.uk/CGI/man-cgi?find
http://linux.die.net/man/1/whereis
what do you mean "probably" a more advanced version? you seem dubious if it's an efficient tool or not

I said probably because I'm somewhat unfamiliar with the complexity of Unix/Linux/whatever search tools.

ah right fair enough

path = gets
path = path.chomp

Why not just:
path=gets.chomp

Isn't it faster that way?

using gets allows for user input without a linebreak, making it look nicer. gets.chomp is more efficient, but I was aiming to tweak design here.
